GIBSON, OF CINCINNATI, OHIO, ASSIGNOR TO GIBSON ART COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO CARD-DECKLIN MACHINE Application filed November 19, 1928.

T he essential object of this invention is to provide a simplified method of producing a rough or deckle edge effect on paper sheets or cards.

A further object is to provide a simple and effective mechanism by which the above outlined method may be carried out.

Further objects and features of the invention will become apparent from the following description relating to the accompanying drawings, wherein I show the preferred form of machine. The essential novel characteristics are summarized in the claims.

Greeting cards and the like are treated to obtain the effect known as deckle edge by various processes, usually including the step of tearing a large sheet into two or more smaller sheets. This, even though several sheets may be treated at once, is very expensive. The present invention is essentially concerned with a novel method of deckle edging wherein the blanks are originally cut to proper size, are held in stacked relation, and the whole stack then operated upon by a tool having an irregular edge, that is to say, an edge, the contour of which is the converse of that desired for the sheets or cards.

In brief, the process, as preferably practiced, comprises assembling a convenient number of blanks in stacked relation with the edges lying substantially in a common plane, clamping the stack in a portable frame, then moving the frame while supported by the stack of blanks across a smooth surface adjacent one edge of which surface the tool operates with a chopping motion toprogressively produce the deckle edge effect on all the blanks in the stack.

The mechanism shown comprises, in brief, a base, the top side of which forms two separated smooth surfaces. Operating between these surfaces is a rotary tool which has its cutting edge suitably indented to obtain the desired sheet or card contour. The blanks are mounted in an open clamping frame adanted to be shifted manually to carry the blanks over the top surfaces of the base and into operating contact with the tool.

A further refinement consists in mounting the stack in such manner that irrespective of justable tables 7 and 8.

clamping pressure on the stack, the latter may be easily turned with reference to the clamping frame to present all four edges, one after the other, to the tool.

Still further refinements of the mechanism include adjustable guiding and supporting means for the stacked blanks by which cards or sheets of widely varying dimensions may be. effectively operated upon in the same machine.

A further feature is the provision of mechanism for sharpening the deckle edging tool, by which the tool may be ground without removing the same from the machine.

In the drawings, Fig. 1 is a side elevation of the machine set up for operation; Fig. 2 is a similar ide elevation of the machine adjusted for sharpening the tool; Fig. 3 is a substantially central longitudinal cross sectional view of the machine with the tool grinding mechanism in operative position; 3 is a fragmentary sectional view of a suitable deckle edging tool; Fig. 4 is a cross sectional view of the machine taken along the line H of Fig. 3,- Fig. 5 is a cross sectional View of the machine taken along the line 55 on Fig. 8; Fig. 6 is a substantially central longitudinal cross sectional view of the blank clamping frame; Fig. 7 is an end elevation of the mechanism shown in Fig. 6, and Fig. 8 is a detail view of part of the blank clamping frame.

Referring again to the drawings, 1 indicates a suitable base upon which rests a plate 2. The plate 2 is extended at one side of the machine as at 2 in Fig. 4 for supporting a suitable driving mechanism for the deckle edging tool as well as for supporting the tool grinding mechanism. Resting on the plate 2 and secured thereto is a hollow sub-base 3, the top portions of which incline toward each other, as suggested in Fig. 3, the edges of the inclined top being suitably formed as at 6 to provide trackways for individually ad- The tables have bridging top members 9 and 10 respectively carrying smooth surfaces over which the stacked cards are slid toward and away from the deckle edging tool. Suitable means, such as screws 12, provided with hand wheels 13 tending arms 27,

arms 28 and engaging ears 5 on the sub-base 3, serve to adjust the top surfaces of the tables relative to each other, if desired, and to the tool.

The tool, as shown particularly in Fig. 3 preferably comprises a plate bevelled at its top edge, as at 20 and provided with depressions 20 preferably of irregular contour and spacing. One or more of these tools may be supported on a suitable shaft 21 p0- sitioned transversely of the machine in suitable bearings (not shown) and arranged to be driven by an electric motor 23 (Fig. 5), resting on the extension 2 of the plate 2. The shaft 21 may be recessed as at 24 to receive the tool and the tool may be adj ustably positioned in the recess by a series of cap screws 25, one being shown in Fig. 3. Adjacent the recess 24 is a second recess 26 arranged to afford clearance for a grinding tool, to be hereinafter described, shown in Fig. 3.

The card or sheet holding and clamping device, as shown particularly 1n Figs. 1, 6 and '7, comprises two end frame members 25 and 26, each having a pair of horizontally exone pair being shown in Fig. 7 and asingle upright arm 28. The serve as handles for shifting the frame over the table surfaces. The members 25 and 26 are joined together by horizontal rods 30, 31 and 32 provided with suitable nuts 33 for spacing the members 25 and 26 in parallel relation, and suitable nuts 34 for holding the members 25 and 26 together.

Journalled in the member 25 is a short axially fixed shaft 35 having an enlarged head at its inner end, designated 36, and a 7 projection .37 on which is mounted a clamping plate 38, preferably wood. The shaft 35 is held in place by a disc suitably keyed to the shaft and overlapping. the end surface of the member 25.

The inner surface of the disc hascircumferentially spaced recesses 41, the recesses being spaced substantially 90 from each other. A suitable plunger 43 seated in the member 25 and acted on by a spring 44 coacts with the recesses 41 to there 'by hold the shaft 35 in various 90 turned positions relative to the frame.

The block of blanks is shown diagrammatically at S in Figs. 1, 6 and 7. The blanks are clamped against the plate 38 and a movable plate 45 similar in construction to the plate 38 and supported on an extension 46 of a short shaft 47 which is in turn supported in the enlarged end 48 of a clamping screw 49. The screw 49 engages internal threads in a bushing 50 rigidly carried by the member 26, and the outer end of the screw may be suitably formed as at 51 for engagement with a wrench.

In order that the block S may be easily turned with reference to the frame, the shafts 35 and 47 are each provided with antifriction thrust bearings 36- and 47*, shown as ball bearings of a common type. The races of the bearing 36 are respectively positioned adjacent the head 36, and the member 25 and the races for the bearing 47 are respectively positioned between a head 53 on the shaft 47 and the enlargement 48 of the screw 49. Suitable means, such as a threaded pin 54, the end of which bears in a peripheral groove 55 on the shaft 47 may be employed to prevent endwise removal of the shaft 47 from the screw while permitting the shaft 47 to turn freely. It will be seen that by the arrangement of bearings and associated parts, the block of sheets or 'cards may be turned as a unit by hand with reference to the frame without releasing the clamping force of the screw, and held in the turned position, so tl at any or all sides of the block may be positioned face down for operation thereon by the deckle edging tool. 7

Suitable means for prevent-ing'the blanks from, becoming freed as by reason of the screw 49 creeping within the bushing 50, in a direction to cause the clamping plate 45 to withdrawn from the blanks, may comprise a may be prevented from axial movement by means of a plate 63 secured to the member 26 and having a bent portion 64 embracing the screw shank and lying outwardly from the wheel, the bent portion bearing directly against a washer 66 which in turn directly engages the wheel.

Suitable means for guiding the block of blanks as the same travels across the top of the machine from one table to another may comprise guide rails mounted on the table members 7 and 8. Preferably the guiding means comprises a T-rail 70 (see particularly Fig. 5) having one surface resting on the tables as at 71. The rail extends across from one table to another and may be supported by brackets 72 (see Figs. 2, 3 and 5) recessed as at 73 to contain the armed portion of the rail and having an overhanging plate 74 completing a slidway for the rail. The T-rail, as shown in Fig. 2, is withdrawn from contact with the table 7 to clear the tool 20 for grinding the same as will be presently shown, and the left hand end of the rail is shown as bevelled as at 75. When the rail is in its normal position (Fig. 1) the bevelled end abuts a fixed guide rail'section 77 secured to the table 7 in registration with the T-rail.

In addition to the guide 70 it is desirable to provide an auxiliary guide on the side of the block of blanks opposite the rail 70 partly to prevent the frame with the block from being accidentally slid off the table onto the floor. Such supplemental guide is shown as comprising a bar removably secured to a horizontal strip 81 supported by brackets 82 fixed thereto, the brackets in turn being supported by transverse rods 83 and 84 in respective tables 7 and 8. The brackets may be secured tightly to the rods and the rods may be longitudinally adjustable in bushing members 85 secured in transverse bores in the members 7 and 8.

The primary purpose of the plate 81 is to support blanks of greater width than are ordinarily operated on by the machine, that is to say, should the blanks be of gerater length than the tool, there should be means to support the overhanging ends of the blanks during their entire travel along the table. The strip 81 and guiding bar 80 may be positioned away from the table a distance determined by the length of the rod 83. Suppose, for exam ple, that the main surfaces of the table measures 8 inches transversely of the machine, then by withdrawing the rods the table width may be effectively increased to support say a 16 inch blank.

When operating on blanks requiring adjustment of the table, as above outlined, part of the block of blanks is deckle edged on one sweep of the blank holding frame across the table, whereupon the frame is turned end for end and the deckle edging completed, as to the remainder of the block. In this connection, it is to be noted that it is within the spirit of my invention to provide for reversing the shaft 21, as Well as the direction of rotation of the shaft driving means, whereby when the frame is turned as aforesaid and the deckle edging operation completed, the burr formed by the deckle edging process on the individual cards or sheets will be uniform. It may be mentioned that with the majority of cards, particularly hard surfaced cards, there is no perceptible burr, hence unusually large cards of this nature may be deckle edged without having to reverse the direction of operation of the tool.

In order that the tool 20 does not have to be removed from the machine each time it becomes dull, 1 preferably provide mechanism for sharpening the tool as part of the machine, but which may be normally swung to a position on the machine in which it will not interfere with the deckle edging operation. Such arrangement, as shown, comprises a slideway affording member (see Figs. 1, 2, 3 and 4) having a depending arm 91 pivotally secured as by a pin 92 to a bracket 93 on the extension 2 of the plate 2. The slideway member 90 supports a base member 95, the lat ter having side extensions 96 engaging beneath overhanging plates 97 on the member 90 which form part of the slideway. The base supports a motor grinder 100. The grinder has a frame 101 provided on its lower side with bevel-sided extensions 102 guided by overhanging parts 103 and 104 on the base 95. The part 104 is shown as removably attached to the base as by a stud 106. The motor frame 101 may be shifted bodily transversely of the slideway 90, to adjustthe grinder with reference to the tool 20, by means of a screw 107 rigid with the member 102 of the motor frame and extending through an ear 108 011 the base 95, there being a hand nut 109 on the screw engaging the ear 108.

The motor casing has an extension 111 supporting the motor shaft 112, and a suitable grinding tool is mounted on the end of the shaft as at 113. The grinding tool, it will be seen, may be adjusted toward and away from the deckle edging tool 20 by means of the nut 109 and the whole grinding mechanism, including base 95, may be shifted manually across the machine on the slideway 90 to grind the whole cutting edge of the deckle edging tool. r

During operation of the grinder, the slideway and associated parts may be held in fixed position above the machine by reason of a member 115 depending from the free end of the slideway member 90 and carrying a pin 116 arranged to be engaged by a hook 117 pivoted as at 118 on a bracket 119 secured to the sub-base 3. The lower end of the member 115 engages the bracket 119 as an abutment. A suitable handle 120 on the endwise extension 95 of the block 95 serves to raise the slideway and associated parts to the position shown in Fig. 1, after the grinding operation is completed.

Suitable means for preventing movement of the grinding motor and supporting base 95 along the slideway when the slideway member 90 is raised may comprise a spring pressed button 122 carried by the extension 9-5 and arranged to engage the end of the slideway as in Fig. 1 or, if desired suitable apertures in the bottom of the slideway.
